Manual transmission oil type

[MKVASMR]

Hi guys. So I have a nasty leak on my end cap and I will be sorting that out in a next couple of days. I have a couple of questions. I took a look and it seems that the shim I seated after the cap. Should it be the other way around? Next thing I will be needing a part number for the cap. The car is 08. 6speed manual.
And the last thing the oil. I can get the G 052 171 A2 from the stealer for around 130€ per bottle! Which is crazy expensive. Other options are the G055 and G060 which are significantly cheaper. Which rout to go with?

There are 2 sizes of end cap, just measure the one you have currently and order that size. 79mm and 84mm iirc.

Don't know what you mean by shim. If you mean shaft play shim kit, you don't need it on an 08 car.  Only 04-06 cars need that.

Use the  G 052 171 A2 stuff.  Yes its expensive but its much better than cheaper alternatives.
